sudheer kiran

thank you for the quick reply.

hi all ,

i have a list of Strings
List<String> list = new ArrayList<String>(); list.add("A_01_B"); list.add("A_02_B"); list.add("A_03_B"); list.add("A_01_C"); list.add("A_02_C");

and a method

public static String fillExpected(String expected, List<String> list){}

fillExpected method should return "A_04_B" when passed ""A_XX_B" as expected String.(Incrementing the value of the int at the positions of XX , considering A and B matching combinations).
and should return "A_03_C" when passed ""A_XX_C" as expected String.

this can be achieved by matchers and wild cards right?
any suggestions please.

There should be only one public class and any number of non public classes, and public class should match with the file name.
you can have all non public classes in a file.

hi thanks for the replies. i just wanted to know if any API is available for quick usage.
i haven't come across a situation but thought of to know if is it possible.

hi all i have some doubts:
1)can we get a list of objects that are presently in memory by passing full class name?
2)can we list classes that are loaded into memory.

thanks,

i have created a jar of my application.
jar contains image files also which i need to send them to report.

first i tried sending file path.but the file it self is comming null when i run jar.
but working fine when i run main class.

MyClass.class.getResource("/img/abc.png");...... did not work when running through jar.

but working with streams
InputStream inputStream = MyClass.class.getResourceAsStream("/img/abc.png");

cant i find a file in my jar??

create a list and pass it to the Collections.unmodifieableList method.
below is from doc
Returns an unmodifiable view of the specified list. This method allows modules to provide users with "read-only" access to internal lists. Query operations on the returned list "read through" to the specified list, and attempts to modify the returned list, whether direct or via its iterator, result in an UnsupportedOperationException.

resolved by setting customized icons.
button.setIcon((ImageIcon)UIManager.getDefaults().get("radio.Icon")); button.setSelectedIcon((ImageIcon)UIManager.getDefaults().get("selectedRadio.Icon")); button.setDisabledIcon((ImageIcon)UIManager.getDefaults().getIcon("disableRadio.Icon")); button.setDisabledSelectedIcon((ImageIcon)UIManager.getDefaults().getIcon("disabledSelectedRadio.Icon")); button.setPressedIcon((ImageIcon)UIManager.getDefaults().getIcon("pressedRadio.Icon")); button.setRolloverIcon((ImageIcon)UIManager.getDefaults().getIcon("rollOverRadio.Icon")); button.setRolloverSelectedIcon((ImageIcon)UIManager.getDefaults().getIcon("rollOverSelectedRadio.Icon"));

i have included xalan-2.7.1.jar and my problem is solved. thank you all.

hey i am too very new to jasper reports...are you using iReport tool to created jrxml...you can check the preview there..

you mean to get every alternative element?...i think we should use counter,for every even number get the element..as far as i know enhanced for loop doesn't have that option
